How to patch a NDS ROM

If you want to play NDS hacks you have to know first how to patch them.
Uploading NDS roms is illegal that's why patches exists.

Things you will need:

  1. The needed clean rom (.nds)
  2. The patch (.xdelta)
  3. Delta Patcher


Once you have everything ready open Delta Patcher and you will see something like this:

Now just select the clean rom in "Original file", the patch in "XDelta Patch" and click "Apply patch"

.patch files

If instead a .xdelta file you have a .patch file that means it has been generated with Xdelta, the "old" way to make patches. To patch a .patch you have to follow the above tutorial and use xDelta GUI instead of Delta Patcher.
